THE GENUS MONODONTOMERUS — GAHAN 481 



scape and pedicel metallic; flagellum black; mesoscutum and scutellum 

 blacl^isli with brassy reflections; pronotum, pleura, all coxae, posterior 

 femora, and propodeum dark green; anterior and median femora 

 brownish black with a greenish metallic lustre; apices of median and 

 anterior femora, all tibiae, and all tarsi reddish testaceous; abdomen, 

 especially on dorsum, black with more or less metallic reflections; ovi- 

 positor black; wings hyaline with a weak infuscation at stigmal vein. 



Head shagreened; temples nearly transverse to longitudinal axis of 

 body; eyes conspicuousl,y pilose; ocellocular line about equal to diam- 

 eter of lateral ocellus; malar space a little less than one-third the eye 

 height; malar furrow distinct and complete; face nearly flat; anterior 

 margin of clypeus very slightly protruded beyond anterior margin of 

 head; mandible with three short, subequal teeth. Antennae inserted 

 distinctly above lower extremities of eyes; scape subcylindrical, not 

 reaching anterior ocellus; pedicel a little longer than broad; ring joint 

 about two and one-half times as broad as long; first funicular joint 

 slightly longer than broad and distinctly thicker than pedicel; follow- 

 ing joints of funicle subquadrate; club veiy slightly thicker than 

 funicle and a little longer than two preceding joints combined. 



Thorax a little less strongly sculptured than head, the sculpture of 

 dorsum consisting of irregular reticulations without obvious pits or 

 pimctiu'es; scutellum about as broad as long, perfectly smooth behind 

 the transverse groove, the punctate marginal groove distinctly inter- 

 rupted medially; postscutellum not or only slightly overlapped by 

 apex of scutellum, smooth and shining and with a strong median 

 carina; median depression on propodeum rather deep, distinctly tri- 

 angular, subacute posteriorly; median carina distinctly divided or 

 forked at base; surface of propodeum laterad of median depression 

 with distinct obliquely transverse rugulae which form narrow elongated 

 areae. Posterior femur moderately broad with tooth on ventral margin 

 rather long, very little broader at base than near apex, and located at 

 approximately the apical one-fourth of femur. Anterior wing extend- 

 ing beyond appex of abdomen; submarginal, marginal, postmarginal, 

 and stigmal veins in approximately the proportions of 29, 15, 9, and 5, 

 respectively. 



Abdomen about as long as thorax, very slightly compressed, reticu- 

 lately shagreened on the sides; first and second tergites perfectly smooth 

 dorsally ; thiid and fourth on apical halves and most of fifth also smooth 

 dorsally, the third and fourth weakly reticulated basally; sixth weakly 

 sculptured and with five or six erect hairs dorsad of spiracle. First 

 tergitc constituting a little more than one-third length of abdomen ; 

 second very short; third and fourth subequal and together a little 

 longer than first; fifth a little over half length of fourth; sixth very 

 short, with the spiracles usually concealed. Posterior margin of none
